Characteristics of log splitter cylinder
1. Piston rod: Our log splitter cylinder uses a piston rod made using 40Cr steel from LAIWU Steel Group (after heat treatment), with a metallographic structure that reaches level 4 or above in Chinese manufacturing standards for agricultural machinery. The surface hardness ranges from 50 HRC-600 HRC, based on customer requests. The Chrome plat surface also has a proven rust resistance after undergoing a 96 hour salt spray test.
2. Sealing ring: from GUARNITEC, Italy, and has undergone a fatigue test 50,000 times with no leaks. The tests have been carried out at a speed of 0.8m/s and a maximum pressure of 40MPa.
3. Cylinder block: The cylinder block is 20# steel form Baoji Steel, and has undergone rolling processing on the in-hole surface with a roughness reaching 0.2-0.4.
4. Cylinder head, piston: 45# steel, CNC processing.
5. Cylinder bottom: 45# forging.
6. Test: test pressure 24MPa, pressure upkeep ≥ 5min, cleanliness of pressure testing oil reaches level NAS9, the weight of internal foreign body <25mg; 100% product test.
7. Coating: spray paint or zinc paint on the surface.
8. Service temperature: -20℃-80℃.
